Filed: 1992-03-26
Abstract: PURPOSE:To surely install a plate frame on a building material in the normal condition by causing a gripping metal fitting to project smoothly without being caught on a leg projecting from the plate frame. CONSTITUTION:A round-type wiring instrument is constituted of a plate frame 1, an inner frame, a switch, a plug socket, etc. A leg 3 is formed on a rear face of the plate frame 1 and then a screw is driven into the inside of the leg 3 from a front face of the plate frame 1. A building material is held by the plate frame 1 and the gripping metal fitting 7 by tightening the screw and then the plate frame 1 is installed on the building material. In this instrument, the projecting length of a longitudinal piece 70 of the leg 3 on the back is made longer than that of a horizontal piece 73. By this method, when the gripping metal fitting 7 is rotated from the stored condition to the projecting one, the metal fitting 7 can be caused to project smoothly without opposition.

Abstract: PURPOSE:To keep the warm air blow-out temperature substantially constant and provide a pleasant, warm room spaces by providing between a heat exchanger and a piping connection adapter an electric motor ball valve with a stepping motor and controlling the opening of the valve and the motor notch. CONSTITUTION:An electric motor ball valve 5 consists of a valve body 5a and a stepping motor 5b, and the valve opening, that is the flow rate of the hot water can be controlled step by step by signals from a room temperature control section.
